AC Performance -8 AN Male Weld-On Bung Fitting (Steel) – Pack of 2
Product description
What it is
AC Performance offers a pair of -8 AN (3/4-16) male weld-on bung fittings in steel. Designed to be welded into a fuel system or other automotive applications, these fittings provide a reliable port to attach AN lines where no flare exists.
What it’s for
If you’re routing AN lines to a location without an existing AN flare, these weld bungs offer a practical solution. Made from steel and intended to be welded, they prioritise durability in demanding under-hood environments, making them relevant for fuel tanks, fuel lines or other automotive configurations where a secure, welded connection is preferred.
How it’s used
The fittings are intended to be welded into a compatible chassis or component where a permanent AN port is required. Once welded, you can thread AN tubing onto the bung to create a sealed connection. The pack of 2 means you can plan for more than one junction or simply have a spare.
Strengths you’ll notice
On the page, the concept is straightforward: a steel, weld-on bung that provides a clean AN outlet without needing a flare. This approach can simplify installation in certain layouts and avoids retrofitting flares into tight spaces.
Limitations and considerations
- It’s a weld-on solution, so it requires welding capability and appropriate gaps to ensure a solid joint.
- Being steel, it will conduct heat and could be more challenging to install in corrosion-prone environments without protective coatings.
- There’s no mention of additional features like anti-corrosion finishes or pre-installed seals, so consider your application environment and whether further hardware is needed.
- For those prioritising a non-weld alternative or a different material, this product may not be the best fit.
Who it’s for
This is likely to appeal to hands-on builders or professional workshops dealing with fuel systems or other AN-based plumbing where a weld-on port is preferable to a flared or push-fit option. It suits projects where space constraints or existing component design make a welded port more practical.
Who it’s not for
If you’re not equipped to weld or you’re after a non-weld coupling, or if you need a corrosion-resistant finish beyond plain steel, this may not be the ideal choice.
Before you buy
- Confirm your AN line size is -8 (3/4-16) and that your intended installation location can be welded with adequate access.
- Check if you require additional sealing hardware or coatings for your operating environment.
- Plan for a clean, well-prepared weld to prevent leaks and ensure durability over time.
Practical usage note
Imagine routing a high-performance fuel line and needing a port where none exists. A weld-on bung can be tucked into a suitable panel or tank wall, then covered with appropriate shielding and fastened securely. It’s not flashy, but if your layout benefits from a welded port rather than fabricating a flare in situ, it’s worth considering.
In context: what else to consider
If you’re weighing alternatives, think about whether a weld-on port is the simplest path to the required AN connection in your build, versus adding a new flare or using an adaptors-based approach. The decision often hinges on space, access for welding, and how permanent you want the connection to be.
Is it worth it?
It makes sense if you specifically need a welded -8 AN port in steel and you have the means to weld it in place. If you prioritise a non-weld or lighter alternative, you may want to explore other options. A practical criterion is whether your project benefits from a robust, permanently mounted AN outlet rather than a serviceable or removable connection.
FAQ
- Do these fittings come with seals or washers? The available details focus on the weld bung itself, no seals are listed, so plan for appropriate sealing methods in your build.
- Can I weld them to aluminium components? The product is specified as steel, welding to aluminium would require suitable adapters or alternate parts and is not covered by the provided data.
- Is a flare toolkit needed afterwards? If your system relies on welded ports, you won’t need to create a flare at the bung itself, but you may still require compatible AN tubing and seals for the rest of the line.
